目的了解第三次全国死因流调四川省5岁以下儿童死亡率及死亡原因。方法利用第三次全国死因回顾抽样调查资料,对四川省10个调查点5岁以下儿童死亡率、根本死因进行分析。结果10个调查点5岁以下儿童、婴儿和新生儿死亡率,分别为12.10‰、7.07‰和4.31‰。各点之间5岁以下儿童、婴儿、新生儿死亡率差异有统计学意义(χ2分别为854.34,364.84,245.18;P<0.01)。婴儿死亡占5岁以下儿童死亡的58.41%,新生儿死亡占婴儿死亡的60.98%。肺炎是5岁以下儿童死亡的第1位死因,起源于围生期的其他情况是婴儿、新生儿死亡的第1位死因。结论新生儿死亡是5岁以下儿童死亡的主要年龄段,肺炎、起源于围生期的其他情况是5岁以下儿童和新生儿死亡的主要根本死因。
Objective To understand the third national cause of death and transfer of children in Sichuan Province under the age of 5 mortality and causes of death. Methods Based on the third national retrospective sampling of death causes, the mortality and underlying causes of death of children under 5 years of age in 10 investigation points in Sichuan Province were analyzed. Results The mortality rates of children under 5 years of age, infants and neonates were 12.10 ‰, 7.07 ‰ and 4.31 ‰ at 10 survey sites respectively. There were significant differences in the mortality rates among children under 5 years of age, infants and neonates (χ2 = 854.34,364.84,245.18, P <0.01). Infant deaths accounted for 58.41% of children under 5 years of age, and neonatal deaths accounted for 60.98% of infant deaths. Pneumonia is the No. 1 cause of death among children under 5 years of age, and other conditions that originate during the perinatal period are the first cause of death in infants and newborns. Conclusions Neonatal deaths are the major age-related deaths among children under 5 years of age. Pneumonia, other origins in the perinatal period, are the major underlying causes of death for children under 5 and newborns.
